Hello I am 57 years old and my BP has been trying to rise for the last 2 or 3 years. Without meds it is about 145/93. I started taking lisinopril 20mg, and it helped but didn't remedy the problem. My doctor added doxazosin mesylate 4mg and raised my lisinopril to 40mg. It was better but he also added hydrochlorothiazide 12.5mg. My pressure is down to 118/68 most of the time now., but my hair has really started to fall out in the last month or so. It was thinning due to age anyway, but this has really kicked it into high gear. I jog and try to eat low fat diet, otherwise healthy. Any suggestions as to what the culprit is? and what to do about it? Thanks
